Japan's Navy and Aid Become More Active in the South China Sea

In what amounts to a Freedom of Navigation Operation (FONOP) Japan will sail 2 of its warships and a submarine from Subic Bay, Philippines (see map above) to Cam Ranh Bay, Vietnam. This will cross China's "nine dash line" (see map below) the vast sea-space (most of the South China Sea) that China claims.

First reported March 6, 2016 in Japanese newspapers and then to other news agencies March 7, 2016 in several news sources here, here and here is news of a Japanese Freedom of Navigation Operation (FONOP) set for April 2016. Pete's summary - These newspaper and news agency reports have likely come
from Japanese military sources who say Japan will be sending an (Oyashio class?)
training submarine and 2 destroyers(?) to visit the Philippines.
They are likely to set out in late March 2016 on Japan’s normal patrol route of the Bashi Channel (Luzon Strait) and reach Subic Bay (now a civilian port) in the Philippines in early
April 2016. They will then sail across the South China Sea to Vietnam’s largest
naval base at Cam Ranh Bay. This will be the first Japanese
submarine visit to the Philippines in 15 years.

China has, by itself, decided to claim most of the South China Sea within its artificial "Nine dash line" (Map above) (Map courtesy GeoGarage).

CHINA'S RESPONSE SO FAR

In answer to “It is reported that Japan's
Maritime Self-Defense Force plans to send a submarine to the Philippines along
with two warships that will then sail on to Vietnam. What is China's comment on
that?” The Chinese Ministry
of Foreign Affairs March 7, 2016 answered: “It needs pointing out that cooperation among relevant
countries should be conducive to regional peace and stability instead of
targeting a third party, still less harming the sovereignty and security interests
of other countries. Japan once illegally occupied China's islands in the South
China Sea during WWII. We are on high alert against Japan's attempt to return
to the South China Sea through military means.”JAPAN'S SURVEILLANCE AID STRATEGY

Rather than confronting China in such a direct way, Japan
instead wants to build the capacity of nations that need help in the region (particularly the Philippines and Vietnam) to improve their
surveillance of Chinese forces. Japanese Defense Minister Nakatani is traveling
to the Philippines in April 2016 to discuss cooperation. This includes providing the
Philippines with several used Beechcraft TC-90 King Air for surveillance of the
South China Sea.

Advice received in early March 2016 on the TC-90 is that
Japan is leasing not granting the TC-90s to the Philippine Navy with Japan and Philippines
to agree on a lease contract in several months. The Japanese government will
not grant aircraft to the Philippines using overseas development assistance (ODA).
This is because ODA is limited to non-military areas and current Japanese law
bans give away Japanese government-owned assets. So the Japanese government
decided to lease the TC-90s which will remain Japanese Navy (JMSDF) property. The value of the lease is
millions yen (US$10,000s) per year.

The TC90s will have no search radars or other devices but
rely on visual monitoring of the Spratly Islands. The TC90 will extend
the Philippines' aerial coverage of the Spratly Islands from the current 300kms
to 600kms – see http://www.yomiuri.co.jp/politics/20160228-OYT1T50110.html?from=ycont_top_txt
(in Japanese). A future Submarine Matters article will talk about Japan's provision of patrol boats to the Philippines.

As the Japanese submarine will be a "training" submarine it may be an older Oyashio class (middle submarine, above). An Oyashio would have slightly less sensitive features than the latest Soryu class (top). Japan can expect that a Chinese (Yuan, Kilo or Song class) submarine will be posted in the Bashi Channel (Luzon Strait) to put the Japanese submarine under surveillance, if possible.
